My invention has for its object a machine for filling bottles and thelike containers, the filling nozzles of the machines being provided atleast with:

(a) a member carried by said filling nozzle and closing the neck of thecontainer to be filled during the filling stage thereof,

(b) a pipe or channel feeding the liquid into the container during thefilling stage.

a tube for setting the inside of the container to be filled incommunication either with the inside of the vacuum chamber of themachine considered or with the inside of the chamber of any compressedgas of said machine;

The invention relates to those filling machines that include moreovereither means for moving the container or containers to be filled towardsor away from the filling nozzle or else a similar movement of thefilling nozzle or nozzles with reference to the container or containers.

The invention relies on the principle of applying a plurality ofdifierent pressures in succession for urging the neck of the containerto be filled against the closing member carried by the filling nozzle,generally made of rubber or the like plastic material; these differentand successive pressures are associated with the relative movementthrough which the container is moved towards or away from the fillingnozzle in a manner such that each of the successive different pressuresmay correspond to one of the stages required for the complete executionof the filling operation desired.

The invention is of considerable interest in a large number of casesinasmuch as it provides for the possibility of giving each of theseparate stages defined by the succession of difierent pressuresassociated with the relative movement between the container and thefilling nozzle, a duration as long as maybe required.

This feature is of great advantage in the case of machines fillingcontainers through application of vacuum with a liquid that shows atendency to frothing as the invention allows in this case leaving theneck of the filled container in fiuidtight contact with the memberclosing the filling nozzle, the liquid feeding channel being closed aslong as may be required. This leaves enough time for the Suction in thenozzle to absorb the froth or excess liquid to be found in thecontainer. Such an application is of particular interest in the case ofmachines filling milk bottles chiefly when the liquid is bottled at alow temperature and has consequently a tendency to froth.

The above mentioned feature is also importan in the case of machinesadapted to fill bottles with beer, lemonade or the like sparkling drinksWhich are generally of the so-called counter pressure or isobarometrictype, the nozzles of said machines being adapted to open and close in aplurality of successive steps:

The first step appears as a consequence of the pressure exerted by theneck of the container to be filled against the closing member for saidcontainer carried by the filling nozzle so as to open the tubecommunicating with the inside of the nozzle with reference to the insideof the chamber of the filling machine that contains a gas under pressuresuch as CO2.

The second step is then provided again through the pressure of the neckof the receiver to be filled against the closing member of the containercarried by the filling nozzle, which has for its result an uncovering ofanother opening in the nozzle that allows then the fiow of the liquidinto said container to be filled.

Such an improvement may for instance be incorporated to machinesprovided with filling nozzles 0f the type disclosed in my prior Frenchpatent, filed on December 21, 1944 and entitled Filling Nozzles forMachines Adapted to Fill Bottles, Flasks and the Like Containers, thelower pressure in the arrangement considered having for its result toovercome first the resistance of the spring closing the valve control--ling the pipe connection between the inside of the container to befilled with the inside of the machine considered that contains CO2 orthe like gas under pressure, the higher pressure having for its objectto overcome the resistance of the spring closing the valve controllingthe actual admission of liquid into the container to be filled.

According to my invention, the bottle filling machine of the typedisclosed in the opening paragraph of the present specification isprovided with means for associating a plurality of difierent successivepressures with a view to urging the neck of the container to be filledagainst the member closing said neck and carried by the filling nozzle,said pressures being applied in succession in'predetermined relationshipwith the relative movement between the container and the filling nozzleagainst the antagonistic pressure of one or more springs opposing theopening of ports provided in the nozzle under the action or saidpressures.

Further it is possible to use two different presmentioned hereinaboveand being substituted afterwards for the higher pressure, such reductionin the pressure allowing the closing of the filling pipe under thepressure of the antagonistic spring, the neck of the filled containerremaining then and for a predetermined duration, in fluidtight contactwith the closing member carried by the filling nozzle; the relativemovement of the container away from the closing member consideredcorresponding to the termination of any pressure urging the neck againstits closing member.

My, invention isalsoapplicable to a vacuum opstated. filling machinewherein the higher; pressure urgingtheneck-againstthe closing member isexerted first so. as. to open the, filling channel while. the lowerpressulfeis then substituted therefor after the filling stage, the neckof the filled container remainingin fluidtight contact for apredeterminedv duration with. the. closing member carried; by; th filng. nozzle, said duration. corresponding to the, time, required forsuckingin the, excesshguid or thegfroth. that may befound mi s-c n a nr.

Lastly, thedifferent successive pressures: appliedare obtained at the.desiredmoment for each container to beg-filled. a distributor for,fluid under pressure feeding a double acting .fiylinder, the. piston ofwhich is securedei-ther to-the carrier of saidcontainerintha case of amovement of the latter with reference. tov the. nozzle or to the nozzlein the case of the latter being mov able with reference to thecontainer. The distributor considered is provided with channels forreceiving and transmitting the fluid under different pressures and itdistributes the fluid in succession and in a predetermined sequenceunder different pressures, each of saidsuccessive distributions of thefluid under a different pressure having an equally predeterminedduration.

It is very important to note that the application of differentsuccessive pressures for urging the container neck against the closingmember carried by the filling nozzle is associated with relativemovementsof the container with reference to the nozzle and thesemovements can only be obtained' in practice through standard mechanicalmembers. It will be remarked on the other hand that for sake of brevity,I will use hereinafter the expression relative movement between thecontainer and the filling nozzle so as to show that the invention isapplicable both to machines wherein the container is movable and tothose. wherein the filling: nozzle is movable.

in. adifierent operative position-of the machine.

In Figs. 1, 2; andS-the members.- illustr'ated are the stator: of the.distributor of fluid under pressure, tharotor 2 thereof and 3 the doubleacting cylinder, the piston 20 of which gives the container 4 itsmovement with reference to the filling nozzle.

The stationary stator i that is freely mounted on the shaft 5 is urgedagainst the rotor 2 keyed to the shaft 5, through a spring 6 orequivalent part.

i designates the pipe feeding the stator I with fluid under highpressure while 8 designates a similar pipe feeding the same fluid undera reduced pressure to the stator I. In this example, the expression highmeans a pressure above that of the antagonistic spring describedhereinafter while low pressure means a pressure less than that of saidantagonistic spring. 9 designates a pipe for the outlet of the fluidpassing out of the stator I.

In the above mentioned distributor stator, the concentric annularchannels It and Il communicate with the channel l2 and are constantlyfed by the pipe l with filuid under high pressure.

The channel it is not connected with the other channels (Fig. 2) and itis fed separately by the pipe e with fluid under low pressure.

The concentric channels It and l5 communicate with one another throughthe channel It. They receive no fluid under pressure and serve only as apassage for the liquid delivered the output pipe 9 With which they arein constant connection.

t should be noticed that the stator I may be held fast against rotationby means of a projection i'l carried by it and adapted to engage a stopl3 rigid with a stationary part of the machine that is not illustrated.

In Fig. l, the pipe 89 operates in alternation to send fluid under highand low pressure underneath the-piston 29 of the cylinder and to receivefrom underneath said piston the fluid urged towards the distributor.

The pipe 2! sends similarly in alternation high pressure fluid to theother side of the piston 2e and receives from said piston side the fluidto be delivered towards the distributor.

In said Fig. l, the piston rod 22 carries the container to be filled 4through the agency of a carrier 23. On the other hand, the fillingnozzle includes a tube 2% connecting the inside of the container withthe inside of a vacuum chamber 46 while a pipe 25 serves for theadmission of liquid and is closed by a closing valve 26 rigid with thetube 24 and the neck of the container to be filled is closed by themember 23 rigid with said pipe 25. The latter slides to a slight extentlongitudinally of the pipe 24 against the action of the spring 2'].

Small vents or ports 29 are provided optionally in the wall of the pipe25 feeding the liquid. The cross-section of these vents is much smallerthan the cross-section of the tube 24 so as to exert no substantialaction on the suction exerted by the tube 28.

They serve as disclosed for furthering the return into said tube 2d ofthe froth or excess of liquid that may be found at the end of thefilling stage in the filled container. Moreover it is possible incertain cases for these vents to prevent adherence through suction ofthe container neck against its closing member 28.

The operation of the arrangement illustrated in Figs. 1, 2 and 3 is asfollows. In the first place, it should be noticed that Fig. 1 and Fig. 2correspond to the stage of application of low pressure on the neck ofthe container to urge it against the closing member carried by thefilling nozzle.

This stage is defined by the angular location of the rotor 2 withreference to the stator I. As a matter of fact, by reason of the rotarymovement of the rotor, the end l9 of the pipe l9 connected with the port30 of the rotor (Fig. 3) registers at this moment with the channel I3fed through the pipe 8, fed in its turn by the low pressure supply thatis not illustrated and may be constituted by a pump, accumulator or thelike means.

Consequently the fluid under low pressure passes through 830-l9 and I3and acts on the underside of the piston 20 but this pressure is lessthan that required for overcoming the pressure of the spring 21 and theneck of the container 4 is urged fiuidtightly against the closing member28 without it being possible for the latter to be raised.

The fluid that is delivered through the other side of the piston 20passes through the pipe 2| and then back through the port 3| of therotor registering with it and then through the channel l5 and theexhaust pipe 9 connected with said channel.

The stage correspondingtoapplication of high pressure for filling thecontainer is prior to the application of low pressure and is executed asfollows: the port 30 of the rotor 2 was lying first in front of thebeginning of the channel II: that is fed in its turn through the channelI feeding high pressure fluid. From this moment onwards and throughoutthe movement of 'the port 30 over the channel It, the fluid underpressure is sent into the cylinder 3 through the pipe I9 and exerts saidpressure on the underside of the piston 26 that transmits it to thecontainer, the neck of which is urged against the closing member carriedby the filling nozzle. But at this moment, the pressure against saidmember being higher than that of the antagonistic spring 2?, the latteryields and the pipe 25 is no longer closed by the valve 26, whereby thefilling operation may be executed.

The stage corresponding to the movement of the filled container withreference to the filling nozzle follows the two preceding stages. It isdefined by the passage of the port 3| of the rotor 2 in front of thechannel II that is fed through the pipe i communicating with it throughthe channels l2 and I0.

At this moment, the fluid under pressure passes through ll0l2 and Handthrough 3| and the channel 2| so as toreach the upper side of thepiston 2| to constrain the latter to sink. At the same time, the fluiddelivered by said piston 20 passes downwardly through I9, 30, I l(registering with 36) I6 and I5 and lastly through 9 that is connectedwith the channel l5.

The example illustrated in Figs. 4 and 5 is similar to that illustratedin the preceding figures except for the fact that the nozzle 24-25 moveswith reference to the container 4 to be filled that assumes a stationarylevel, the stage illustrated being that corresponding to the filling ofthe container.

In Figs. 4 and 5, the same members have retained the same referencenumbers as precedingly and the operation is as follows:

By reason of the rotary movement of the rotor 2 with reference to thestator I, the end of the pipe 2| connected with the opening 3i of saidrotor has come into register with the channel l0 fed through the pipe 1,fed in its turn by the high pressure source that is not illustrated.Consequently the high pressure fluid passes through r -l n 3 li'l intoEr e 'iiiifnk ii' eab ve the pis ton 20. T e latter; the i'fid 22oftvhiehis new with the filling nozzle 'censjtrains saie ndz'zleto moveinto the egntaineij to be filled-and the closing member 28 carried bysenescent: engages the neck of sai container.

But as the distributor fiir fluid unqefpressure is at this moment in thestage at Which it distributes high pressure fiuid the actieiri exertedby the upper part of 'the filling nozzle on the spring 21 overcomes theresistance of the latter so that'said spring 21 yields,- the feeding ppe 25 he longer (Emmet with the valve 26 and m aning eperatien may seem.

I p vided with a liquid I02 therein, suchas beer, for example, and the space I03 above the liquid in the tank isfilled with a gas under pressure, such as, for example, carbon dioxide.As is clear from Figs. 6 and '1, an elongated tube H5 has a top open endlocated in the space I03. This tube H5 is fixed at its bottom end to amember H6 covering an opening H1 in the bottom of tank I85 and formedwith a bore IIB which is a continuation of and communicates with thetube H5. Member He has a bottom extension IE9 formed with radial bores52%? communicating with the bore IE8. To. the bottom end of extension II9 is fixed an elongated guide member lZI formed with one or moregrooves I22 and carrying at its bottom end an enlargement W3. A tubularmember Ii! has a lower portion slidably mounted on member I2I and anupper portion III" slidably engaging the extension H9, this member IIIbeing enlarged just below the upper portion III thereof to form a spaceit? located about the bores i20 and the top end of grooves 522, as isclearly evident from Fig. 5. The lower end of member III is formed withan enlargement It! adapted to engage enlargement I03 for closing thepassage of gas from space N33 to the interior of bottle I0 3- throughthe tube H5, bore H8, bores I26, space I23, and grooves 522. Whenenlargement I87 of member Iii is spaced from member I08, as illustratedin Figs. 6 and 7, the interior of bottle I0 3 is in communication withspace I63 through the above-described path. The upper end II! of memberIII is threadedly connected to member I2 5 which is mounted for slidingmovement along member H63, and spring Iili engages at one end thereofmember H8 and at the opposite end thereof a flange I2 3 of member I24 tourge the latter and n'ir-unber- I ll therewith toward enlargement IE3 soas to tend to maintain enlargement Iii? of member HI against enlargementI633 to prevent flow of gas from space W3.

A tubular member H0 is fixedly connected to a circular member 525 whichis mounted for sliding movement along the lower end portion I25 ofmember I24, this member IEO forming between itself and member III anannular space communicating with the space I21 defined by members I2d,I25 and the portion of member I I i beneath the top end IIi thereof.This space I27 communicates through a bore I23, formed in member 42-1,and a bore iZii, formed in member I10, with the bottom of tank It! sothat liquid I62 is free to fall through bores #29 and 523 and fill thespace I27 and the annular space between members III! and Hi. A springIE9, stronger than spring I06, bears at one end against member I25 andat an opposite end against flange I24 to urge the bottom end of memberII?! against enlargement It! of member III, as shown in Fig. 6, toprevent liquid I32 from flowing from tank itl. Located about member I Itis a sealing ring I05 adapted to engage the mouth of a bottle ISA whichis to be filled.

The piston means 26 and the valve means and hydraulic circuit connectedthereto are identical with the structure shown in Fig. 1.

When rotatably mounted valve member 2 is in the position where lowpressure line I communicates with the piston 2d, the support 23 movesthe bottle me against the sealing means I05 with a force great enough toovercome the force of spring I06 but not great enough to overcome theforce of spring I09 so that enlargement I8! is thereby moved upwardlyaway from the enlargement I08 to the position shown in Fig. 6 so as topermit gas in space I03 to flow into bottle I 04, as described above,and wash any air out of the bottle. In this way the trapping of any airbubbles between the liquid which flows into the bottle and the sides ofthe bottle is avoided.

Upon continued rotation of valve member 2, the high pressure line 8 isplaced in communication with piston 20 so as to move, with a forcegreater than that of spring I09, support 23 and bottle ii -4 thereonagainst the action of spring I09, thereby axially moving member IIIIupwardly away from enlargement I01 to the posi tion shown in Fig. 7, sothat liquid I02 may flow by gravity through bores I29 and I28, throughspace I2! and the annular space between members I IE3 and II I and intothe bottle I04.

Upon further rotation of valve member I02, high pressure line 8 is cutoff from piston 20 so that spring I09 then moves tubular member H0 backto the position shown in Fig. 6 where the flow of liquid I02 is cut ofi.The hydraulic fluid is then permitted to flow through discharge line 9to permit support 23 to be lowered for the removal of bottle I04.

In the present description, the term fluid has been used for designatingthe medium used for transmitting difierent pressures and movementsthrough the above mentioned distributor, said fluid may be constitutedby compressed air or the like gas under pressure. It may also beconstituted by a liquid such as oil for hydraulic movements, said latterarrangement being preferred.

Of course, the distributor considered may be of any type whatever suchas a disc, cone, cylinder, valve or the like type, provided it allowsthe successive application of the diflerent pressures required forurging the neck of the container to be filled against the closing membercarried by the filling nozzle, said different pressures being associatedas disclosed hereinabove.

It is even possible to apply the different operative pressures otherwisethan through a fluid under difierent pressures. However this lattersolution is the most convenient chiefly in the case where the inventionis applied to vacuum operated filling machines.

In this case, as a matter of fact, the distribution of fluid underdifierent pressures, preferably under hydraulic control as disclosed,allows filling in any haphazard sequence containers even of varyingheights without the duration and amplitude of the operative stage underlow pressure being modified through said difierences. This is due on onehand to the fact that the closing of the filling channel is producedbetween application of high and of low pressure and is always providedby a relative movement of same amplitude whatever may be the height ofthe filled containers; on the other hand, the duration of the suctionstage for the excess liquid or froth is also of constant amplitudewhatever the height of the containers.
